Sniper

npc_sniper is a point entity available in the Half-Life 2 series. This Combine soldier is wielding a sniping weapon with a blue laser sight, making it capable of extreme accuracy at extreme range.

The npc_sniper does not actually have its own model - rather, it uses a Combine soldier model in-game (if its Hidden flag is not set) playing its idle animation, with the rifle's laser coming from the center of the hull. Only explosions and burning damage can hurt the sniper.

The sniper doesn't turn on his sight until after he sees the player or an NPC within an acceptable range and angle, and will turn it off again after he is done. He will prioritize the player over any other target. If he loses track of the player, he will get frustrated and shoot three rounds at the area where the player was last seen, often targeting smaller prop_physics (like soda cans, melons, melon chunks, cinderblocks, ...) but not large prop_physics (like soda machines). He will then resume to targeting any other visible targets.

Note:Some keyvalues, flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.

Tip:The sniper will pay attention to info_snipertargets if ordered to (with the SweepTarget, SweepTargetHighestPriority or SweepGroupRandomly inputs).

This entity is also tied to proto_sniper.

In code, it is represented by theCProtoSniperclass, defined in theproto_sniper.cppfile.

Keyvalues

BaseNPC:

Relationship <string> !FGD

Changes whether this NPC likes or dislikes certain others. Used like the ai_relationship entity, with this NPC as the subject. Format: <string|targetname or classname> <string|disposition> <int|rank>.

Values for disposition are:

D_HT: Hate
D_FR: Fear
D_LI: Like
D_NU: Neutral

Target Path Corner (target) <targetname>: The path_corner that this NPC will move to after spawning.

Squad Name (squadname) <string>: NPCs that are in the same squad (i.e., have matching squad names) will share information about enemies and will take turns attacking and covering each other.

Hint Group (hintgroup) <string>: Hint groups are used by NPCs to restrict their hint-node searching to a subset of the map's hint nodes. Only hint nodes with matching hint group names will be considered by this NPC.

Hint Limit Nav (hintlimiting) <boolean>: Limits NPC to using specified hint group for navigation requests. Does not limit local navigation.

Sleep State (sleepstate) <choices>

Holds the NPC in stasis until specified condition. See also Wake Radius and Wake Squad.

0: None
1: Waiting for threat
2: Waiting for PVS
3: Waiting for input, ignore PVS
4: Auto PVS
5: Auto PVS after PVS

Wake Radius (wakeradius) <float>: Auto-wake if player comes within this distance.

Wake Squad (wakesquad) <boolean>: Wake all of the NPCs squadmates if the NPC is woken.

Enemy Filter (enemyfilter) <targetname>: Filter entity to test targets against.

Ignore unseen enemies (ignoreunseenenemies) <boolean>: Prefers visible enemies, regardless of distance or relationship priority.

Physics Impact Damage Scale (physdamagescale) <float>: Scales damage energy when this character is hit by a physics object. With a value of 0 the NPC will take no damage from physics.

Base:

Name (targetname) <string>: The name that other entities use to refer to this entity.

Parent (parentname) <targetname>: Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (parentname [targetname],[attachment])
Tip:Entities transition to the next map with their parents
Tip:phys_constraint can be used as a workaround if parenting fails.

Origin (X Y Z) (origin) <coordinates>: The position of this entity's center in the world. Rotating entities typically rotate around their origin.
Note:Hammer does not move the entities accordingly only in the editor.

Pitch Yaw Roll (X Y Z) (angles) <angle>: This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
Note:This works on brush entities, although Hammer doesn't show the new angles.

Classname (classname) <string> !FGD: Determines the characteristics of the entity before it spawns.
Note:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!

Flags (spawnflags) <integer> !FGD: Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.

Effects (effects) <integer> !FGD: Combination of effect flags to use.
Entity Scripts (vscripts) <scriptlist> (in all games since ) (also in ): Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions. Scripts executed on the worldspawn entity will be placed in root scope.

Think function (thinkfunction) <string> (in all games since ) (also in ): Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Avoid expensive operations in this function, as it may cause performance problems.

Lag Compensation (LagCompensate) <boolean> (in all games since ) !FGD: Set to Yes to lag compensate this entity. Should be used very sparingly!
Is Automatic-Aim Target (is_autoaim_target) <boolean> (in all games since ) !FGD: If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.

BaseAnimating:

World Model (model) <string>: The model this entity should appear as. 128-character limit.

Skin (skin or ModelSkin ) <integer>: Some models have multiple skins. This value selects from the index, starting with 0.

Collisions (solid) <choices>: Method of collision for this entity.

0: None
1: BSP (QPhysics) !FGD
Bug:In Portal 2, if an entity using QPhysics collisions is hit by Gel, the game will crash!
2: Bounding Box
3: Oriented Bounding Box (Use for runtime spawned rotated brush entities) !FGD
4: Oriented Bounding Box, constrained to Yaw only !FGD
5: Custom/Test (Usually no collision with anything) !FGD
6: VPhysics

Hitbox Set (hitboxset) <string> !FGD: Sets the $hboxset to use.

Body Group (body or SetBodyGroup) <integer> !FGD: Sets the the active $bodygroup.

Model Index (modelindex) <short> !FGD: Given the number index from dumping the cl_precacheinfo modelprecache table, sets entity model to the index.
Warning:If an entity has animations that will be played, then the set model also must have its own sequences, else the game crashes.
Model Scale (modelscale) <float> (in all games since ): A multiplier for the size of the model. Negative values are accepted. Does not alter the physics collisions in most cases, however.
Warning:Negative or extremely high values can cause crashes!
Note:Scale may not appear in Hammer 4.x, but will appear in-game (tested in ). This is fixed in Hammer++.

Animating

Sequence (sequence) <integer> !FGD: Default animation sequence for the model to be playing after spawning.

Playback Rate (playbackrate) <float> !FGD: A multiplier of the framerate at which animations are played, negative values are accepted. Default is 1.0.

Cycle (cycle) <float> !FGD: The current frame of the current animation, on a range from 0-1.

Texture Frame (texframeindex) <integer> !FGD: The initial frame number for all animated textures on this entity.

Effects - Render

Start Fade Distance (fademindist) <float>: Distance at which the entity starts fading. If 0 or less, the entity will disappear instantly when end fade is hit. The value will scale appropriately if the entity is in a 3D Skybox.

End Fade Distance (fademaxdist) <float>: Distance at which the entity ends fading. If 0 or less, the entity won't disappear at all. The value will scale appropriately if the entity is in a 3D Skybox.

Fade Scale (fadescale) <float>: If specified in the worldspawn, or if the engine is running below DirectX 8, entities will fade out even if the fade distances above aren't specified. This value gives more control over when this happens: numbers smaller than 1 cause the entity to fade out at further distances, and greater than 1 cause it to fade out at closer distances. Using 0 turns off the forced fade altogether. See also $noforcedfade.

FX Amount/Transparency (0–255) (renderamt) <integer>: Transparency amount, requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.
